| Research Abstract |
Experimental work was done for organic light emitting diodes (OLEDs) which are highly efficient and functional. An OLED with four exciplexes showed a super-broad band quite similar to solar radiation spectrum. Another OLED with a charge generation layer inserted between blue fluorescence emitting layer and yellow phosphorescence emitting layer showed high efficiencies of 120 cd/A and 50 lm/W. Single molecule which emits multi-color light was successfully synthesized for not only polymer but also small molecule.
